“Our ability to care for these patients requires attention to their primary medical problems.
Those patients often have significant comorbid diseases and need procedures of varying complexities. as well as understanding these devices”.This will increase the chances to be confronted with patients having CRMD (not uncommon).
.

which senses the intrinsic P wave and causes inhibition or triggering of the pacemaker. thus maintaining A-V synchrony.

Atrium is paced and the impulse passes down the conducting pathways.Single Chamber Atrial Pacing (AAI. Useful in sinus arrest & sinus bradycardia (adequate AV-conduction) Inappropriate for chronic AF & long ventricular pauses.. Atr.

Never intended to treat pacemaker emergencies or prevent EMI effects
.
Magnet-activated switches were incorporated into pacemakers to produce pacing behavior that demonstrates remaining battery life.Effect of the Magnet Application on Pacemaker Function.

Magnet application results in a non-sensing asynchronous mode with a fixed pacing rate (magnet rate).
Use of magnet during surgery is not without risk. (diathermy/cautery). magnets can be used to protect the pacemakerdependent patient during EMI.Thus. Asynchronous pacing may trigger malignant rhythm.
